@sam mods Rear part, this one around tail lights and licence plate, should be/could be made with carbon fiber material (your one is simply grey colour) http://ss-vette.com/wp-content/uploads/2016/07/dodge-viper-gen-5-rear-spoiler-carbon-fiber-ss-vette-preview-3.jpg
and front badge on the hood should be blacked out https://s1.cdn.autoevolution.com/images/news/why-we-love-the-srt-vipers-vented-hood-79314_1.jpg or http://hanabi.autoweek.com/sites/default/files/styles/gen-1200-675/public/910009999-9_0.jpg

If anyone has got a problem with spawning etc, I just wanted to mention that proper line for dclist.xml should be like below:

<Item>dlcpacks:\vipergts\</Item>

If someone wants better POV inside the car (lower=more realistic) should change "z" value in vehicles.meta to this one:

@sam mods I appreciate your update, tho... imho wheels still could be improved (rims are too bright, they could be more intense in changing colour, I mean how I could get more dark grey or black rims?; they could be nicer modeled as rim stick out a bit off the tire, here is sample from real life http://www.motorward.com/wp-content/images/2014/07/Dodge-Viper-Time-Attack-8.jpg) besides, tinting is still not working properly. Template for liveries could be attached.
Thanks for your work anyway

@sam mods oh c'mon man - you can do almost everything as a modder. Rim should go bit inside the tire while tire/rubber should be more rounded at tge edge http://www.auto-tuning-news.com/uploads/photogallery/supercars/dodge_viper_srt_gts_2013/dodge_18_030412.jpg

@sam mods I'm just giving you some feedback and you are sending me back for some additional wheels pack? Wheels putted on your mod are totally too small, too narrow. If you dont want to put some more work on your wheels thats fine, I'll pass too. But they ain't proper.

@BKDeath2012 are they? let's see... let's compare @sam mods m1 and current viper wheels: https://imgur.com/WwUckwIm1's wheel is nice, clean and round; rim is bit inside the tire (like irl); viper's wheel is edgy and rim is sticking out of the tire. Plus I just wished rims could be available to paint just like m1's look like. Besides I noticed that valve on the rim has got weird chrome place which stands out to the whole rim (around valve there is a rectangle with different material)

@sam mods Could you at least make more darken outer part of the rim spokes? Because under_silver.dds texture changes only inner part of the rim. There could be one additional texture to control it just like under_silver - so everyone could adjust it :))) Please?
I also suggest to rebuild .rpf archive as it weights 115mb (vehicles.rpf) while yft's and ytd weight around 40mb.
